MPEG This sequence zooms in on an optical image of the central region of The Antennae, then dissolves to a Chandra X-ray image of the multimillion-degree-gas clouds in this system. The image next dissolves to a sequence of images that shows hot gas clouds where the abundances of iron (red), magnesium (green), and silicon (blue) atoms are greatest. The final image is a composite of the three abundance maps. [Run time = 0:16 sec]
